The STAR Plus System is designed for convenience and flexibility, freeing the analyst from the time-consuming tasks involved in sample preparation.

The system automatically adds reagent to the vessels according to the requirements of the programmed method. The reagent is added in aliquots while the digestion is running to prevent cooling the digestate. The system’s proprietary pump technology ensures that an accurate measurement of reagent is delivered instantaneously on demand. Each reagent has a dedicated pump for every cell eliminating any mixing or cross contamination of reagents.

The system is comprised of individual cells that operate independently of each other, allowing different methods to run simultaneously or with staggered start times. Each vessel has its own cell with temperature feedback control. The vessel cells are positioned along a waveguide, which provides a conduit for the microwave energy generated by the magnetron. Each cell has its own proprietary microwave aperture control. An open aperture allows the microwaves to enter the cell, while a closed aperture prevents it. The temperature feedback system monitors and controls the energy supplied to each cavity based on the requirements of each method, initiating the opening and closing of the apertures automatically as needed.
